To all 'whom it may concern.'

Be it known that I, J Aims State of Kansas, have invented 'certain new and usefullmprovements in Battery' Terminals; and I do declare the following t0 be a full, clear, and exact ldescription ofthe in ventin, such as will enable `others skilled in the art to which it appertains tov make and use the 'same,.reference being had to the 'accompanying drawings, and to the figures lof reference marked thereon, which form a part of this'specifcation. Y.

This invention relates to secondary battery terminal connections and the primary object thereof is to provide a battery terminal protector which will prevent t e electrolyte in the battery from contactingwith the terminal and thereby insulating the cable from the battery post due to corrosion.

The clamps for the cables frequently corrode due to the fact that the electrolyte spills out of the cells of the battery and Aforms a corrosive substance which has poor conduc` tivity, the result being that the cable is insulated from the posts to such an extent that the current flow is opposed; furthermore the corrosive substance freezes the clamp to the l0 battery post so it is dilficult'to remove.' My invention contemplates a protector which will prevent the electrolyte from coming into contact with the terminal or post so that it will remain clean and devoid of the objectional corrosive substance. To this end the. invention consists of providin a housing which encloses the terminal an protects the same from deterioration by the elements. The novel constructiony of my invention will be apparent by referring to the accompanying drawings, in Which Fig. 1 is a fragmentary perspective view of a secondary battery to which my invention is applied.

Fig. 2 is a sectional view on line 2:2 of.

Fig. 3 is a plan view of the invention. Fig. 4 is a perspective view of the enclosing housing with the cover removed, and

Fig. 5 is a fragmentary perspective view of the cover. Y

Referring now to the drawings by numerals of reference, l designates one end of a secondary battery having a post or terminal CQ BALDWYLN,v a citizen ofthe United States, residingat Junction City, in the county of Geary andl 2 of usual construction,.v Such terminals are usually tapered, that isthey `are in the form'` of truncated cones and usually the cable ',i's.

f'fastened directlyto them. .In the present instance however, I fprovidejanl enclosing housing having an upstanding wall 4 eX- tending entirely around the edge of the bottomj 5, the Wall being adapted tc .receive a cover 6. t rI he bottomvplate 5 has an upstand ing 4tubular lmember Z which fits over the post-or Fterminal 2. The member 7 receives the clamp 8 of vusual construction to which vis fastened, inthe. usual way, the cable 9. ,The cable extends through an insulation block 10 lhavin a groove 11v on three sides which receive t 1e edge 12 ofk a lblock receiving' opening 13. The opening 13 is in effeet aslot cut in the wall of the housing to l receive the block'. The block vextends outxv wardly from the wall of the housing due to the fact that the Wall is received in a groove in the edge of the block, so thev cover 6 is provided with an offset portion or extension '14, the edge of the extension andthe edge of the mam'- body portion being provided with adeep cover flange 15 which its over. the edge/ of the block and over the edgeof vthe lhousing.v It will be'a-ppare'nt that the terminal and the clamp will be entirely enclosed vby the housing` and its cover so that the electrolyte cannot contactwith the termi. -nal and sothat the terminal and the Aclamp sov will be protected from deterioration by the elements. .If desired the housing maybe packed vwith grease or some other suitable Y material although ordinarily this will not necessary. Y. l

The tubular member is preferably welded to the post 2 thereby providin a solid connection to the post and the aci is prevented from entering the housing fromthe bottom, consequently -theobjections Yheretofore en,- countered and to which'attention has been called in the first .part of thisv descriptionwill .be eliminated. y

What I claim and desire to secure by Letters-Patent -is 1. A secondary battery connection comprising a housing havin ,an upstanding tubular member carried "its bottom to engage the battery post "terminal by fitting over the terminal, the memberL'having an outer face to receive a cable clamp and a removable cover for the housing.

2. A battery terminal connection comprisinga housing having a bottom and a side Wall extending around the. edge of the bottom, the bottom being provided with a tubular member to it over the battery post terminai and an insulating block carried by the wall of the housing provided with an opening to receive a cable.

3. A battery terminal connection comprislng a housing having a bottom anda sidewall extending around the edge of the bottom, the bottom being provided with a tubular member to fit over the battery post terminal, an insulating block carried by the wall of the housing provided with an opening to receive a cable and a removable cover Acarried bythe upper edge of the Wall of the housing.

4. A battery terminal connection comprising a housing having a bottom and an upstanding Wall carried by the bottom, the

Wall having a slot, an insulating block se- 'cured 'to the edge 'ofthe slotzand an upstanuing tubular member carried by the bottom to tit over the battery post.:

5. A battery terminal connection comprising a housing having a bottom and an upstanding Wall carried by the bottom, the wall having a slot, an insulating block secured to tbe'edge of the slot, an upstanding tubular member carried by the bottom to fit over the battery post and a cover having a deep ending flange overlapping the housing and the battery post terminal and the block. ln testimony whereof aiix my signature.
